Abstract

PURPOSE:To obtain external parts for a pocket timepiece having superior corrosion and wear resistances and assuming a fine golden color, by implanting gold ions into the surface layers of parts coated with titanium nitride. CONSTITUTION:Titanium nitride films are formed on external parts made of stainless steel or the like for a pocket timepiece by ionic plating or other method. Gold ions are implanted into the surface coating layers by an ion implantation method, and the implanted gold is optionally diffused by heat treatment in vacuum. The amount of gold used can be made <=about 1/100 time the amount required by gold plating, and a fine color tone can be provided like gold.

発が望１れていた。Conventionally, the thickness of the gold plating must be at least 5 μm to ensure wear resistance and corrosion resistance during long-term portability. Gold is a commercially available metal, and it has been desired to develop a gold-colored coating that is easy to manufacture and inexpensive, making effective use of limited resources.

を特徴とするもので必る。However, these colors have a slightly dark tone, unlike the color of gold itself. This is because the reflectance at each wavelength is on average 15% lower than the color tone of the tray. Although it is made of a 10,000-gold alloy, it is not real gold, so there is a limit to its sales as an ornament, which means that the color tone is slightly dark. : There were two drawbacks: limited sales due to unreasonable costs. The purpose of the non-invention was to eliminate the above-mentioned drawbacks of the conventional technology, and a portable device coated with titanium nitride was developed. ``[It is characterized by the fact that gold is injected into the surface layer of the peripheral device ItS product.

していた。Example 1 A titanium nitride coating with a thickness of 1 μm was entirely formed on a stainless steel wristwatch case by ion blasting. Next, the watch case was placed in the gold ion implantation device and gold ions were implanted into the entire surface layer. The implantation conditions are an accelerating voltage of 100 KeV.
, injection type is lX101ons/C++! Met. In addition to implanting ions into each site, the device is equipped with a sample rotation mechanism. The reflectance at the trough wavelength of the de-timed H-F case obtained in this way increased to a value of 1, which is almost the same as the reflectance of gold itself, and exhibited a beautiful color tone equivalent to that of gold.

1 The color tone was closer to gold than the result of Example 1. The maximum concentration of gold implanted into titanium nitride is at a depth of about 0.1 μm, and the ## of gold is rather small at the outermost surface. In order to soften this concentration gradient and darken the gold concentration at the outermost surface, thermal diffusion was used in the upward movement.

。In addition to this invention, there are methods such as injecting gold into the golden hard lower layer and further heat diffusion.
- To obtain all the tones of true gold, the gold used in the field is less than 1/100th of the cost and cost of conventional gold plating, and is injected with extremely pure gold (pure gold) that has been subjected to mass spectrometry analysis. It can also be expected to have a decorative advertising effect. The uninvented golden exterior parts for mobile watches that have these effects have excellent corrosion resistance and abrasion resistance, and exhibit a beautiful golden color, so they can be applied to a wide variety of decorative purposes.
